Agent

the Grand Overseer of Sangvis Ferri, she relays commands given by the Mastermind to all entities Sangvis Ferri. Classification of Agent is a Rear Command type Android (后方指挥人形) despite her powerful combat performance, her typical role within SF is communication and logistic network management, it is hinted she also takes care of Elisa's daily life needs, and Elisa relies on Agent a great deal. Agent sits at the top of the SF command hierarchy ladder just below Elisa and has direct command privilege over all SF entities.

Overall behaviour of Agent is described as ruthless, but not manner-less, this calm and level headed Overseer would speak with respectful tones to both friends and foes alike. However her choice of vocabulary varies depending on audience, she only speak with polite and respectful words to her Master, against enemies and incapable subordinates she speaks in a more vulgar tongue. She seem to be holding extra prejudice against G&K.
